world--to hide their heads beneath the bed-covering. Brutus, when
Caesar's ghost appeared beside his couch, before the battle of
Philippi, sat up and stared upon the horrid apparition, and suffered
correspondingly, when it would have been much easier and more
natural to put his head under his pillow, and so shut out the
unpleasant spectacle. That is the course I have invariably pursued,
and it has never failed me. The most luminous ghost man ever saw is
utterly powerless to shine through a comfortably stuffed pillow, or
the usual Christmas-time quota of woollen blankets. But upon this
occasion I preferred to await developments. The real truth is that I
was about written out in the matter of visitations, and needed a
reinforcement of my uncanny vein, which, far from being varicose,
had become sclerotic, so dry had it been pumped by the demands to
which it had been subjected by a clamorous, mystery-loving public. I
had, I may as well confess it, run out of ghosts, and had come down
to the writing of tales full of the horror of suggestion, leaving my
readers unsatisfied through my failure to describe in detail just
what kind of looking thing it was that had so aroused their
apprehension; and one editor had gone so far as to reject my last
ghost-story because I had worked him up to a fearful pitch of
excitement, and left him there without any reasonable way out. I was
face to face with a condition--which, briefly, was that hereafter
that desirable market was closed to the products of my pen unless my
contributions were accompanied by a diagram which should make my
mysteries so plain that a little child could understand how it all
came to pass. Hence it was that, instead of following my own
convenience and taking refuge in my spectre-proof couch, I stayed
where I was. I had not long to wait. The dial in my fuel-meter
below-stairs had hardly had time to register the consumption of
three thousand feet of gas before the faint sound of a bell reached
